An administrator has migrated a vCenter Server Appliance from version 5.5 to version 6.x. During the migration, the administrator selected DHCP for the appliance and obtained a hostname from the DHCP server. The administrator adjusts the hostname after the migration and uses a static IP and hostname.

What should the administrator do immediately after this change to prevent service failures?

Regenerate the SSL certificates.

Re-register components to Single Sign-On.

Update the /etc/hosts file.

Execute the command services.restart vmware-vpxd.

Answer: A Explanation:

To resolve this issue, regenerate the vCenter Server certificate using a stronger public key strength.

An ESXi 6.x host in the vCenter Server inventory has disconnected due to an All Paths

Down (APD) situation. An administrator has corrected the APD issue on the host, but it still remains disconnected.

What action should the administrator take next?

Select Restart Management Agents from the DCUI.

Execute esxcli system settings advanced set -d /Scsi/FailVMIOonAPD.

Modify the advanced parameter /Disk/ApdTokenRetryCount.

Enable the advanced parameter /Misc/APDHandlingEnable.

Answer: A Explanation:

If the ESXi 6.x in vcenter server inventory has disconnected due to APD, you have to restart management agents from the DCUI.

Users are reporting CPU related performance problems on the virtual machine Email-Prod throughout the day.

The resource settings for the VM and the ESXi host the VM is running on are shown below: VM:

->Email-Prod

->vCPUs: 4

->Memory: 96GB

ESXi host:

->CPU: 2 x 8 Core Processors

->Memory: 128GB

->NUMA rchitecture. 2 Nodes

Which two options would alleviate the observed performance problem for Email-Prod? (Choose two.)

Enable the advanced parameter Numa.PageMigEnable.

Enable the advanced parameter Numa.AutoMemAffinity.

Enable CPU affinity to separate 2 vCPUs for each NUMA node.

Enable CPU affinity to bind all vCPUs to one NUMA node.

Answer: B,C Explanation:

Address the performance problem for email prod by enabling advanced parameter numa.automemaffinity and CPU affinity to separate 2 vCPUs for each NUMA node.

Refer to the Exhibit.

Review the Exhibit. An administrator has configured permissions for a group called VMGroup and a user named VMUser. A new Role has been created called PowerVM. The group and role have these charecteristics:

->PowerVM role can power on VMs

->VMGroup granted PowerVM role on VMFolder

->VMUser is a member of VMGroup

->VMUser granted No Access on VMFolder

Based on the exhibit, which statement best explains why VMUser is denied access to the VMFolder?

The VMUser permission overrides the VMGroup permission.

The No Access role overrides the PowerVM role.

The VMGroup permission overrides the VMUser permission.

The PowerVM role overrides the No Access role.

Answer: A Explanation:

->Give No Access to the user at the vCenter Level.

->Go to the particular cluster you want to give permissions for. Then click on the permissions tab of that cluster and give the user Administrator access(or whatever role you intend to give). It will ask to override the inherited permissions, say Yes.

->Now when the user logs in, he/she will see only one cluster under the vCenter.

->No access will remove the visibility to the object

Refer to the Exhibit.

An administrator wants to increase the capacity of a VMFS5 datastore; but the Increase Size by slider is not available, as shown in the Exhibit.

How should the administrator resolve this problem?

Select a valid partition configuration from the drop-down menu.

Use fdisk utility to manually resize the partition.

Use the mouse to resize the partition indicated in the Partition Layout.

Clicking Next will prompt for available usable space.

Answer: A Explanation:

To increase the capacity of VMFS5 datastore, you can select the drop down menu on the right panel and select a partition configuration that can help increase the capacity.

An administrator is experiencing network connectivity issues between virtual machines. The virtual machines and hosts are configured as follows:

->VM1 is running on Host1

->VM2 is running on Host2

->Both Host1 and Host2 are attached to the vSphere Distributed Switch dvSwitch1

->Both Host1 and Host2 are using vmnic0 and vmnic1 on dvSwitch1

->Both virtual machines are using the default portgroup for network traffic

What are three settings the administrator should investigate while troubleshooting the connectivity issue? (Choose three.)

VLANs of the physical NICs

Failover order of the uplinks

Virtual NIC connectivity to the dvSwitch

Security policy of the portgroup

Traffic shaping on the portgroup

Answer: A,B,C Explanation:

To find out connectivity problems, you can use VLANs of the physical NICs, virtual MIC connectivity to the dvswitch and failover orders of the uplinks.

A vSphere Web Client task fails while creating a VMFS datastore on a disk with these characteristics:

->The disk was formatted with an Master Boot Record (MBR) partition table

->The disk was not erased

->The disk is visible in the vSphere Web Client

What action needs to be performed to resolve the issue?

Delete the partitions manually with partedUtil.

Create a VMFS3 file system first, then upgrade it.

Create a VMFS5 file system with the command esxcli storage filesystem add.

Delete the data with the vmkfstools command.

Answer: A Explanation:

You can use the partedUtil command line utility to directly manipulate partition tables for local and remote SAN disks on ESXi and ESX.

The partedUtil command line only is supported for disk partitioning from ESXi 5.x. The command line utility fdisk does not work with LUNs formatted with VMFS5.

Deploy the virtual machine template to the cluster and allow Distributed Resource

Scheduler to register the virtual machine.

Answer: A,B,C Explanation:

Slow performance while deploying a virtual machine template can be annoying. To address this problem, you can increase network throughput by adding uplinks to the vSwitch. You can also change the destination datastore for the virtual machine template. Similarly, you can configure provisioning traffic vmkernel port to do the deployment operation.
